just searching and it seems we can co exist 2003 and exchange 2010 and use 2010's owa and active sync while talking to the datastores provided by 2003.

whats the best way to go about this? how many machines are required to be setup ?

there is a project on at the moment to look at hosted solutions but it wont happen before we swap our devices (i hope not at all but thats a different matter !) i have about 4 weeks to get this done and working

I'm server/storage rather than exchange but exchange is now my responsibility too as its seen we will do better than the last team. I've been using 2k3 since 2004 roughly but I've no experience of anything newer at the moment. Any guidance would be great to implement an 2010/13 mail front end to our existing backend. I have a month roughly till our blackberry contract terminates so I need to be in and testing within 2 weeks really. It will be hosted on ESx I hoping if I can get this in and working we will prove our self's to the buisiness.

We would need them anyway thankfully that's something that's not mine to worry about

I agree ms licensing is very easy to make mistakes with and is sure as hell not cheap !
